Its interrupting capacity hits 187 kA at 240 V AC and 121 kA at both 415 V and 440 V — numbers that put it squarely in high-fault-duty distribution, not light branch protection. At 690 V the same breaker still clears 4.25 kA, so it covers 480 V and 600 V class panels with headroom to spare. The thermal derating curve is published: full 100 A holds through 50 °C, then steps down to 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C. That matters for a panel pulling near-rated load in a hot enclosure — the 50 °C ceiling is the real-world limit before you lose ampacity. ## Trip unit and auxiliaries — what is inside the can The ETU320 electronic trip unit gives adjustable thermal-magnetic-like curves but with better accuracy and selectivity coordination. No communication function, no phase failure detection, no ground fault monitoring — this is a plain line-protection breaker, not a power monitor. The basic switch insert is order code 3VA2110-5HL32-0AA0, and the integrated auxiliary trip module is 3VA9688-0BL33 — useful to know if you are stocking spares or replacing a failed subassembly without swapping the whole breaker. Max power loss 10 W — negligible heat contribution in a populated panel, but worth noting if you are packing breakers tight in a sealed enclosure.","metaTitle":"Siemens 3VA2110-5HL32-0KH0 SENTRON MCCB, 100 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2110-5HL32-0KH0 molded case circuit breaker, 100 A, 3-pole, ETU320 release.
